ALBERT F. AIv'IES, OF BATTLE CREEK, MICHIGAN.

LUBRIGATOR.

Application filed October 14, 1912.

To all whom it may concern:

Be it known that I, ALBERT F. AMEs, a citizen of the United States, residing at the city of Battle Creek, Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to improvements in lubricators.

My improved lubricator is especially designed by me as a lubricator for car journal boxes and I have illustrated the same herein embodied in such a structure. It may, however, be readily adapted for embodiment in other structures.

The main object of this invention is to provide an improved lubricator for journal bearings which is automatically discharged into the box when the bearing becomes unduly heated and one which may be readily recharged with lubricant after having discharged its supply.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a detail perspective view of a car journal box embodying the features of my invention. Fig. II is a detail vertical section on a line corresponding to line 2-2 of Fig. I. Fig. III is a detail horizontal section on a line corresponding to line 33 of Fig. I. Fig. IV is a longitudinal section through one of the feed passage screws 4 on a line corresponding to line 4-4 of Fig. III, the fusible plug 5 being shown in full lines. Fig. V is a detail section corresponding to that of Fig. II, of a modified construction, the lubricant receptacle being formed integral with the journal box instead of separate as shown in Figs. I, II and III.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

The receptacle 2 is secured to the journal Specification of Letters Patent.

box by means of the screws 3 and 4E. The screws 4 are disposed near the bottom of the receptacle 2 and provided with longitudinal bores or feed passages therethrough. These feed. passages are normally closed by the fusible plugs 5, the plugs being preferably threaded into the screws 4:. The outer wall of the receptacle is provided with openings alined with the screws 3 and 4: and through which the screws and the plugs 5 may be manipulated. This is for convenience in attaching the receptacle 2 and for renewing the fusible plugs 5. The openings in the outer wall of the receptacle 2 are closed by the threaded plug closures 6.

The receptacle 2 is preferably divided into compartments by a vertical partition 7, there being a feed passage connecting each compartment with the journal box. The fusible plugs for the two compartments being spaced at considerable distance, it is unlikely that both will be fused at the same time so that only one compartment is discharged at a time.

The cover 8 is common to both compartments and is held normally closed by means of the spring 9. This spring is coiled about the cover pintle 8 with one end resting against the journal box securing bolt 12, and the other engaging the cover. See Fig. I.

The bearing 13 for the journal 10 is retained by the keys or wedges 14 as is customary.

The journal box is provided with the usual packing of waste 11. In the event of the bearing becoming unduly heated, the plug 5 is fused and the lubricant admitted to the journal box. The plugs 5 are of any suitable material adapted to fuse at the desired temperature.

In the modification shown in Fig. V, the

receptacle 2 is formed integrally with the journal box, the feed passage for the plug 5 being in the wall of the journal box.

The form shown in Figs. I, II and III is adapted as an attachment to journal boxes now in use as it can be readily applied, it only being necessary to tap on the side walls of the journal box to receive the attaching screws.

I have not attempted to illustrate or describe the various modifications in structure which I contemplate as such modifications and adaptations will be readily understood by those skilled in the art to which this in- I as claiming my improvements specifically,in

the form illustrated as Well as broadly Within the scope of the appended claims.
